And now to a wild police chase through city streets in California. Slamming into a cafe, inches away from customers outside. David Kerley looks at how close this came. Reporter: Watch. It's the end of a police chase. As the suspect vehicle slams on to a northern California sidewalk. One coffee shop patron pinned against the wall. Turned a four-door car into a two-door car. Reporter: The man driving the car, wanted for alleged domestic violence in sausalito. Two police cars chased the suspect for a mile. Injuries only here. But just last week, a car being chased by Houston police crashed into another vehicle. Six dead in all. Chases happen every day, and on average, one person dies every day. 342 killed in 2012. A reminder for Jonathan Farris, whose son was an innocent victim in a police pursuit. Oftentimes protecting the public means breaking off and not continuing that pursuit. Reporter: Most departments have policies governing when and how to chase a suspect, many based on guidelines the international police chief association approved 18 years ago. And now in 24 jurisdictions, this starchase system. An officer shoots a gps tracker beacon onto the suspect car, allowing them to watch where the bad guy goes, without being in hot pursuit.
